A Casanova heat pump has to work at 3 below and stand clear of 30 inches of snow.
Electricity is the most common heat around Casanova. In ZIP 20119, the Census area the village sits in, just over half the owner homes heat with it, and in a house built since the 1980s that usually means a heat pump outside and an air handler with backup heat strips inside. The typical owner home in the ZIP dates from about 1990, so plenty of those outdoor units have already been swapped once and are coming due again.
Sizing starts with winter. On the morning of January 27, 2026, the weather station at Warrenton-Fauquier Airport, about five miles south, read 3 below zero. At Warrenton 3 SE, the nearest NOAA normals station, about five nights a year fall to 10 or lower, and the median spring freeze doesn’t pass until around April 9. A heat pump’s output falls as the air gets colder, so the question for a new one is how much it still puts out on those mornings and how much gets left to the strips.
Snow decides where it sits. In the January 2016 blizzard a CoCoRaHS observer about five miles west-southwest of Casanova measured 30 inches on the ground, and the Weather Service logged 18 to 30 inches across southern Fauquier. A heat pump melts the frost off its coil over and over in that weather, and the meltwater has to drain away instead of freezing under it. Out here the outdoor unit belongs on a stand or a wall bracket above the drifts, and out from under a metal roof that sheds its snow in one slide.
Casanova has no public water, so every house runs its own well pump, and that pump shares the electric panel with the heat pump and its strips. Before a bigger heat pump or a bigger strip kit goes in, the panel and the air handler’s circuit get checked for room. When the lines come down, as they did across the county in the March 2, 2018 nor’easter, an all-electric house loses its heat and its water at once, so if you run a generator, the heat pump belongs in that plan too.
Casanova houses, by the numbers

When a heat pump in Casanova is worth replacing.
The backup heat light never goes off in January
Strips running all day usually mean the outdoor unit isn’t carrying its share: low refrigerant, a defrost that’s failed or a compressor that’s worn out. The $99 diagnostic visit finds which before anybody prices a new one.
Aux heat is on all day
When the heat pump can’t keep up, the electric strips take over, and they cost far more to run. Aux heat on for hours is the sign.
It’s past 15 years old
It heats all winter and cools all summer, so it piles up hours an air conditioner never sees. Past 15 years, price the replacement beside any big repair.

How to pick the best heat pump installer in Casanova.
Questions to ask anybody who quotes you, us included.
What does it put out on a single-digit morning?
The big heating number on a spec sheet is rated at 47 degrees. Ask for the output down near 5, where Casanova’s coldest mornings sit, next to what your house loses on those mornings. A big gap between the two means the strips do the work.
Did they size it, or copy the old label?
Copying the old nameplate repeats whatever guess was made when the house was built. The wrong size runs worse in both seasons.
Is the air handler in the price?
A heat pump system is the outdoor unit plus the air handler inside. Ask whether the quote covers both, matched, in writing.
Who sets up the backup heat?
Set wrong, the electric strips run on mild days. Ask who programs the thermostat and at what outdoor temperature the strips may come on.

Heat pump replacement questions from Casanova.
Should the heat pump be paired with a propane furnace?
If the house already has a propane furnace or a tank, it’s worth pricing. The heat pump handles the cooling and most of the heating, and the furnace takes over on the coldest mornings instead of the strips. A furnace and air conditioner together run $8,898 to $23,000; the HVAC replacement estimator prices your house each way.
Will a heat pump keep up when it’s 3 below?
Not by itself, and it isn’t meant to. On a morning like January 27, 2026, most heat pumps sized for this area hand part of the load to the backup heat. Sized right for the house, that’s a handful of mornings a year, not the whole winter.
How much does heat pump replacement cost in Casanova?
$8,499 to $21,650 installed for a heat pump system, the outdoor unit and the air handler, 2 to 5 ton. A small single-stage system lands near the bottom, a big variable-speed one near the top. The HVAC estimator narrows it to your house.
Should I get a heat pump, or a furnace and air conditioner?
A heat pump system runs $8,499 to $21,650 installed; a gas furnace and air conditioner together, $8,898 to $23,000. No gas line usually means a heat pump. With gas, you can keep the furnace and add one; our heat pump vs gas furnace guide runs the numbers.
